DRA-2 UNIVERSAL COMMUNICATION NODE

USER GUIDE - Rev.5 (January 2018)
The master router regularly sends VRRP advertisement packets to the backup routers. If
the backup routers do not receive the VRRP advertisement packets for a time that is three
times the established period, they assume that the master router has fallen and commence
a process for selecting a new master.
The equipment supports the simultaneous execution of multiple instances of VRRP
protocol. Each one is configured into an individual register, whose parameters are
described below.

time for supervising the master when it acts as a backup router. The default value
is 1 second.
•
VRRP I/F.
This establishes the interface on which the VRRR protocol will be
executed.
